Efergy Pro vs ONESHOT Ballistics

View your production and consumption from anywhere! The Efergy Pro allows you to track not only your solar panels’ daily energy production, but you can also track your home electricity usage, how much energy you’re importing and exporting. This can save you a huge surprise when the electricity bill arrives! Without the information that the Efergy Pro provides, you can easily dramatically underestimate how much power you are drawing from the grid.
